Question

Make a sign diagram for the function and determine all x-values at which relative maxima occur. ​  ​
E)no relative maxima

Quizplus · Accepted Answer

The sign diagram shows that the function is negative to the left of -3, positive between -3 and -1, negative between -1 and 1, and positive to the right of 1. This indicates that there is a relative maximum at x= -2 and another relative maximum at x= 2. The correct choice is D, which depicts these two relative maxima on the graph.
